There are also varying levels of drunk. At the legal limit in some places, some people might show very little impairment at all. It's impossible to compare without saying what level of alcohol or cannabis they're talking about and for what person with what tolerance. People react differently and consume different amounts.
- Retric 7y agoThat’s a reasonable objection. The best data I could find is a ~2% increase in reaction time from a 10% increase in BAC. That suggests the range from legally drunk to unconscious is surprisingly narrow at least in terms of reaction times. I did not really dig into it, but these devices might actually be strictly worse from a reaction standpoint. At least until the driver is loosing consciousness.
